3338. Several days ago, while I was excerpting passages I had written concerning auras, because I was without any feeling caused by an aura, I did not then know what an aura is, nor did the spirits around me know, so that it was as if they did not exist. Then I was led almost to feeling that there were no such things as auras. This taught me how people on earth see it, namely, that such things can never be, because they have not been taught by any sense.
